2 Claims.

s; heating unit for the heating .of hot water which is so'constructed that it may be readily mounted 'inipresent constructions of fireplaces and thereby 1 absorb the "heat energy usually wasted in such nates the hollow bottom of a water jackeirstrucfireplaces for heating of not only the room in E'. 15 which the fireplace 'is'mounted, but also addi- I tional or all of the rooms in the'house.

A further object of'this invention is to correct faults which have heretofore been present in constructions whereby the circulation of water of air pockets, ,thelocation of which was not I readily detected.

A 'still further object of this invention is to -='provide a heating unit wherein relatively flat and r; "substantially parallel plates may be used in the formation of the water jacket without impeding the circulation of water through the heater.

' --heating' unit constructionembodied in my co- 3 pending application filed July 2'1, 1933, Serial No. j 681,628, and is an improvement over the structure "embodied in that application.

Referring now to-the drawings, and'first to Figures 7 to .12 inclusive, thenumeral20desigture, 2 designates the hollow sides',"22i designates 15 generally the rear hollow wall, and '23 designates thehollow front. wall above'theopeningffl in the front of the unit. 7

.The bottom comprises aninnerplate or wall 25, and an outer orlower plate 26 whichis held. in spaced relation t'othe inner plate-'25. by.means of studs or spacing membersZ'l- Thesestuds or spacing members 21 may be secured to .the' walls 25 and 26 as by/Iwelding 28 or'the like so' that Water may freely circulate..between .these' two 25 members; '2 The front edgesiof the bottom: wall members are connected together as by a front This invention is a continuation in part-of the.

plate 29. V

' As will be particularlynotedfrom'Fig. 12 the inner bottom plate 25 is disposed on an inclination to the horizontal andis inclined relative'to the horizontal'rbottom plate 26;;the inclination being in an upward direction from. the front .plate 29 toward therear walljstructure..22. In

other. words the .space between'theinner'plate V .and this heat has a tendency to cause buckling or warping of theiplate so that where this plate 40 25 is parallelwiththe bottom plate 26 fa trap is formed. in the bottom of the .heating unit which will not only impede but prevent the cir- "culation of water; By the plate becoming. warped,

towards the other plate, the plates 'are' nearer toeach other at this "point of warping than elsewhere. Thereby, the circulation is impeded. In 'fact, part of the water is trapped. *This'trapping orstagnation of 'water; even where the inner bottom wall becomes distorted, is prevented 5 in the present construction by mounting the inner plate 25 on a rearward and'upward-inclination, which inclination is in the direction of the flow of the-water-from' the front to the rear of the hollowbottom. '55

The rear wallstructure 22. comprises an inner or forward wall or plate 30 having its lower edge secured to or integral with the adjacent edge of the inner bottom plate 25. The inner or forward wall 36 has'the lower portion there'- of substantially vertical, and the upper portion is bent forwardly as at 3i. A rear or outer. wall member 32 is disposed in spaced parallel relation 7 to the inner rear wall member 30. -The upper portion of. the fear or outerwall 32 is bent forwardly as at 33. This rear wall 32 has its low- 'er,edge secured to or integral with the adjacent rear edge of the bottom plate 26, so that water may flow'freely from the bottom through the rear 'wall structure. The wall members "30-3I and 32- -33 are maintained in spaced par:

' allel relation by studs 21, which studs are'used wherever needed in the present construction to hold confronting plates apart; A top plate 34 is secured to the upper edges of the plates 3 land 33.

' An' inner end wall" plate35 .is secured at its lowerredge'to theinner bottom plate 25, and is Lsecure'd at its rear edge to the forward or inher rearwall 30. There are two of these plates 35, one at each end of the bottom, and the plates 35 are mounted in rearwardly convergent relation; An 'outer end wall plate 36 is disposed spaced parallel relation to the inner end wall member.35,- and has its loweredge sesecured to the back plates'32'33. As shown in cured to the'bottom plate 26, and its rear. edge Figure-6, the u per ends of the plates and .36 are connected by. atop wall 31.;

f The front jacket or wall 23 comprises an 1nu .fner'wall or plate 38 and an outer or front wall orplate 39. secured at their ends to the end wall plates 35 and 36 respectively. .A top plate 40 is securedto the upper edges of the plates '38 and'39 and .a' bottom plate 4| is secured to the.

lower edges ofthese" plates as and -39;

Anintake nipple 42. s secured to the'bottom plate 26, and if desired two of these nipples 42 .Qmayibesecured to the bottom plate 26 so that connection may, be'made with the bottomof the '1"? ple 43 is secured to theouter end wall member unit adjacent either-end thereon An outlet nipl 31 adjacent the upper end thereof, and if desiredeach end wall may have an outlet nipple,

eerher water'may be exhausted fromthe unit 5' received'into'the unitfrom either or both ends."

from? either.- er both. ends, and the watermay .be

K ash discharging chamber.44 isprovided throughthe bottom 20, and a trap door 45 normally .closes this chamber or passage .44.. The front edges ofthe end iwall-memberse35jand 36 arev connected by a front plate 46.

Referring now to Figures l and 2, the heat fi ing" unit hereinbeforedescribed is adapted to be' f mo.unted"in, afireplace structure designated F,

insulated from the fireplace F by means of inand the rear and ends of. the unit are preferably sulation I of suitable character. The front openingj24. of.'the unit may be closed by a closure orjclosures generally'designated as 41, which may rbe. either. hinged to the front of .the'unit .or to the opposite sides'of' the'fireplace structure, or may be mounted in any other desired manner for rno ve rnent into open or closed position. The clo- 7 sure preferably comprises a transparent body section 48, anda lower damper section 49,

Thel outlet nipple '43. atone end of the unit is connected as by a pipe 50 to an expansion tank 5 and the hotwater is then distributed by suitable pipe connections toradiators remotefrom 7 fireplace, preferably just above the top of'the' heating unit, and the damper 53 is operated by and or operating member 54' extending forwardly through the front of the fireplace F2. As will be noted from Figs. 3 and 5 the inner bottom plate 25 of 'the heating unit is'pr'eferably flush with the hearth so that as viewed from the front the fireplace "F" does not give the appearance of a hot water heater. Andirons or a grate may, be

used with the'heating unit, and if desired an ash tray or pan 55,.as shown in Figure 12, may be used to initially catch the ashes; which maybe either removed through the front of theunit or droppedthrough the chamber 44.[

It will be apparent from the foregoing fthlat a heating unit has been disclosed whereinethe' plates comprising the inner and outer'walls' of thejacket can be made from sheet metal of suitable thicknes s, or'if'd'esiredmaybe constructed from cast metal.. Prefer'ably' howev'er, the unit is constructed from sheet metal suitably formed and Welded or otherwise sealed;

simplicity of its construction can be manufactured and installed at low cost, (and due: to. the

. simplicity of its construction itcan bereadily mounted in present fireplace constructions, or

can be added at the time the building is under 7 construction. This heating unit is not only de-' signed as a means for solely. heating a house but it can be used as an adjunct or booster to present hot water heating systems'whereafireplace isjavailable. 1 With a heater: of this type it is not necessary to mount it in a'relatively low point, as in the cellar,qin orderto obtain'the desired circulation, so that this heating unit can be used in houses without cellars but having ,fire-' places, and at the sametime the entire house is maintained at the desired temperature. 2

This heater as will be noted from the drawings, can be used on thesame level with the radiators, and at the same time a. circulation: throughout the heating system is maintained so thatall of .the radiators will be heated, which has: not heretofore been possible with a heating unit mounted as hereinbefore describedp= r It is obvious that various changes and miodifi-f V cations may be made in the details of construc-,

tion and design of theabovespecificallydescribed embodiment of this invention without departing from the spirit thereof, such changes andmodifications being restricted only by the scope 'of the annexed claims. l 2

Instead of wood, as shown, coal, oil, coke,,gas,

-electricity or other heating material can beused.
